Teams allows you to "log in" using multiple email addresses. By default it will associate with your MS account you use to log into Windows. However if you received a computer from your employer AND they have an MS subscription that includes Teams (most do) then you can log into Teams using your work account. You can also remove your edu account.
To do all this:
- Start Teams
- Click on your profile icon in the top right and then
Add another account
. - Add your work account (note this may require permission from your company's network team.
To remove an account:
- Ensure you are not signed into the account.
- Click the settings button.
- Go to
Accounts and orgs
. - Click the account(s) you want to remove and then click Manage.
- This takes you to a website where you can leave organizations.
- Note that an organization can configure this so you cannot leave it. In that case you need to contact the organization to get removed. See here.
A last resort would be to uninstall Teams which should wipe your sign ins. You could then reinstall Teams and not sign into the given account. However if the machine is managed by an organization then it'll just sign you back in anyway.
